Final answer:
American farmers made a great deal of money during World War I and World War II due to increased demand for agricultural products.
Step-by-step explanation:
The war that allowed American farmers to make a great deal of money was World War I.
During the war, European countries involved in the conflict needed food to feed their soldiers and citizens. The United States became a major supplier of agricultural products, including wheat, corn, and meat, which led to a surge in demand and higher prices. American farmers benefited greatly from this demand and were able to make significant profits.
The increased demand for American agricultural products continued into World War II, where farmers once again played a crucial role in supplying food to the war effort.
